SPECIFlCATION forming part of Letters Patent No..546,63 4, dated September 17, 1895. Application led April 23, 1894. Serial No. 508,728 (No model.) Patented in England May 18,13931N0 91952- To a/ZZ whom it may concern.-
Be it known that I, HARRY CHRISTOPHER ATKINS, engineer, a subject of the Queen of Great Britain, residing at 27 Agamemnon Road, West Hampstead, England, have inventedImprovementsinFiltering Machinery, (for which I have obtained Letters Patent in England, No. 9,952, dated May 18, 1893,) of which the following is a specification.
This invention relates to machinery for the continuous filtration of water in large orsmall quantities, but primarily has for its object the iiltering of large quantities of Water, such as town supplies, and may also be used, if desired, for separating the solid matter from sewage-water, manufacturers refuse, or for the like purposes.
This invention comprises a large tank or vessel into which is fed the water or liquid to be filtered or treated, a large drum or 'cylin-l der having a solid periphery and adapted to revolve on its longitudinalV axis in said tank and almost but not quite totally immersed in the said water or liquid'in said tank, a number of holes or openings through the periphery of said drum, a number of separate collecting areas arranged on the exterior of the drum by having a series of channels or grooves (either longitudinal, diagonal, radial, or otherwise) formed on the outside of said drum and specially arranged with reference to said holes or openings, and which serve to collect the water or liquid as same comes through the filtering medium and conduct it readily and quickly to said holes or openings, pipes or passages inside the drum leading from each said hole or opening or from several of same .to a collecting-box bearing or hollow axle of the drum, a spring-mounted non-rotating hollow plug or valve around which the said collecting-box of the drum revolves, a longitudinal division or divisions in said hollow plug, means to shut off connection or close one (or more) such collecting-pipe (or pipes) when same is (or are) in the uppermost positione., when the hole or holes to which it leads in the periphery is out of Water or nearlysoacircular stationary chamber or pipe inclosing said valve-spindle at one end to receive the iiltered liquid from said collecting-box and at its other passing through the end of the tank and terminating inadischarge-pipe outside the tank, and around this said chamber or pipe inside the tank a stuffing-box carried on said closed drumrevolves with the latter, an endless band of cloth or other suitable liltering material adapted to pass around the eX- terior of the said drum and thence through a suitable adjacent washing apparatus and back to the drum, and various other details of improvement, all of which will be fullydescribed hereinafter, and inally pointed out in the claims. y
ln the accompanying drawings, Figure l is an end elevation and Fig. 2 a plan of my improved machinery. Fig. 3 is a cross-section of the apparatus on line l l, Fig. 2, looking in the direction of the arrow z. Fig. 4 is a longitudinal vertical section on line 2 2, Fig. 2. Fig. 5 is a view online 3 3, Fig. 4, looking in the direction of the arrow y, showing the several collecting-pipes coming through the end of the drum and convergingtoward and terminating in the collecting-box, but omitting the bearing-bar e". Fig. 6 is a local view, on an enlarged scale, (i. e., longitudinal section,) on line 4 4, Fig. 4, showing the special construction of thel valve. Fig. 7 is an end View of Fig. 6. Fig. 8 is a cross-sectional view on line 5 5, Fig. 6. Fig. 9 isa cross-.sectional view, Fig. l0 an end View, and. Fig. ll alongiltudinal sectional view, all on an enlarged scale, of a modified construction of valve.
Similarletters of reference indicate corresponding parts throughout.
Figs. l to 8 illustrate a filtering-machine,
vhaving on the solid rim or periphery of the drum or cylinder a a number of longitudinal `and diagonal collecting-channels a', the said periphery of the drum @being divided into a number of longitudinal collecting areas, each of these areas being arranged to act as or subdivided into several local collecting areas, each of these latter being provided with a local hole or opening a, through the periphery into the interior of the drum a, each such hole being fitted with a branch pipe b', leading into one of the collecting-pipes b, connected to and discharging into the collecting-box c, the interior of which latter is of conical or tapering form and Iitted with a hollow valve or skeleton plug h of similar form,` which latter is spring-mounted, as hereinafter explained.
The solid rim orperiphery of the drum or cylinder o, is plain for a short distance near each end am', but the intervening surface is IOO provided and covered with ribs or grooves and channels ct a', so arranged as to divide the surface into any desired number of collecting areas, as before described, presenting a channeled or furrowed surface for the endless band of filtering material to rest upon, so that the filtered liquid can travel underneath it to the openings or outlets a a, which latter are advantageously provided with a grid to prevent the filtering-cloth being drawn in.
Each longitudinal collecting area is separated from the next by a plain space or rib a" a, extending longitudinally from one plain end ot` the periphery to the other.
The collecting-pipes b l) are arranged inside the cylinder, there being one pipe for each longitudinal collecting area and a branch b b', attached to each said opening or outlet a a. One end of the pipe is closed, but the other discharges into the collectingbox c c, formed at or nearthe end ofthe cylinder a. The interior of this collecting-box c is of conical or tapering form internally, as shown in Fig. 4, for the purpose of receiving a hollow valve or skeleton plug h of corresponding tapering form and intended to tit therein. This plug is shown in position in Fig. 4, and more fully in detail in Figs. 6, 7, and S. The front end consists of a ring h', titting the large end of the inside of the said hollow bearing. The small end h is a disk or it may be a ring also. The two ends are joined by a circular-shaped roof-piece or septum L", which fits against the top of the said bearing, and is fully shown in Figs. G and 8. This top piece or septum L" serves to close one or more openings or terminals ot' the pipes bin the collecting-box c as same arrive at or near the topmost position, so that a vacuum can be maintained throughout the collecting-pipes and collecting areas, which are below the surface of the liquid, and thus each part of the periphery is cut off when saine comes to the topmost position as the drum revolves. A rib 7t connects and strengthens the two ends. This skeleton plug 7L does not revolve, and is held in position by being secured to one end of the rod l. The opposite end of the rod Z has a collar thereon (which latter fits over two studs on the end cover and the spring Z. This latter, through the rod [,presses the plug h against the interior of the collecting-box c, and, as it is commonly expressed, keeps it up to its work.
Figs. l and 5 show aportion of the endless band of filtering material o o, nearly surrounding the cylinder a a. lVhen at Work lterin g, the cylinder a is intended to revolve slowly. The cylinder is caused to revolve by motion being imparted to the spur-wheel e", mounted on the back vaxle d of the drum a. The drum is carried by the said back axle or trunnions d and the front hollow trunnions e, resting on bearings or bearing-bars e c, on which latter the said drum revolves. e is a gland or packing by which the said hollow trunnion c is fitted onto the discharge-pipe 7c, on the exterior of which it is thus adapted to revolve. k is the outlet from the discharge pipe k, whence the filtered water is led away in any desired manner. The usual water-level is shown at w w. The filtering material o o is led onto the cylinder a by the roll o', travels with it as it revolves, and is led off on approaching the top, as shown by the arrows.
Figs. 9, lO, and ll show the construction of the plug when it is desired to separate the filtered liquid discharged into the collectingbox c as the cylinder revolves, and thereby obtain separate qualities of filtration. The plug m is of conical or tapering form to fit the interior of the collecting-box c, as before. The large end m and small end m are solid disks joined together by the longitudinal divisions m', the number of which is governed by the number of compartments it is desired to form. In Fig. 9 four compartments are shown with a separate pipe n connected to each, as shown in Figs. l() and ll. The four pipes pass along the main discharge-pipo l.: and terminate at the end cover la or in other convenient manner, and may be springmounted, if desired, in which case cach pipe n would pass through a stuffing-box in the end cover 7c, and thus the valve would be automatically kept up to its work, as before, or same may be otherwise suitably adjusted. The top compartment may be open, as shown, or closed over by means of a piece, like the septum 71 in Figs. 6 and 8, in which latter case its corresponding pipe n would be dispensed with.
The operation is as follows: The liquid to be filteredis fed into the cistern f f in any suitable manner and filters through the material 0 while the latter is traveling, leaving the impurity or deposit on the outside of the material. The material conveys such impu rities deposited thereon out of the cistern to any convenient receptacle or cleaning apparatus. The filtered liquid passes along the grooves on the outside surface of the cylinder to the openings a" a, then into the pipes b l), is conveyed by these to the hollow bearing c, and thence through the skeleton plug 71, into the main discharge-pipe 7c, Figs. 1, 2, and 4, and is delivered outside the cistern f. The branch 7c may be extended, so as to give the filtered liquid a certain fall, or the suctionpipe ot a pump is connected. By either means any desired vacuum can be obtained, and not only is filtration facilitated in several ways, but some liquids of a very clogging nature can be filtered, which without the aid of the vacuum is difficult if not impossible.
